LLaDA-Image Base — ComfyUI INT8 + GGUF

Quantized LLaDA-Image Base weights for the RealRebelAI LLaDA-Image ComfyUI custom nodes.

Based on inclusionAI/LLaDA-Image, this release is intended for lower-memory ComfyUI inference while retaining the Base model workflow.

ComfyUI Custom Nodes

https://github.com/RealRebelAI/LLaDa-Image_ComfyUI

Install into:

ComfyUI/custom_nodes/ComfyUI-LLaDA-Image/

Restart ComfyUI after installation.

Upstream Model

Included Weights

Base INT8 Transformer

LLaDA-Image-Base-transformer-INT8.safetensors

Place in:

ComfyUI/models/diffusion_models/

This is a native INT8 Safetensors transformer, not a transformer GGUF.

Base Q4_K_M Text Encoder

LLaDA-Image-Base-text_encoder-Q4_K_M.gguf

Place in:

ComfyUI/models/text_encoders/

The custom runtime uses City96 ComfyUI-GGUF support for the quantized LLaDA2 MoE text encoder.

Requirement

Install City96 ComfyUI-GGUF:

https://github.com/city96/ComfyUI-GGUF

VAE

Place the compatible LLaDA VAE in:

ComfyUI/models/vae/

Then select it in LLaDA Image Loader.

The current custom nodes expose native VAE tiled decoding:

vae_tiling:
On
Auto
Off

For low-VRAM GPUs, On is a good starting point.

Base Recommended Settings

Steps: 50
CFG:   5.0

LLaDA-Image Base is the full model rather than the distilled few-step Turbo variant.

Text-to-Image

LLaDA Image Loader
        |
        v
LLaDA Image Text to Image
        |
        v
    Save Image

Loader example:

diffusion_model: LLaDA-Image-Base-transformer-INT8.safetensors
text_encoder:    LLaDA-Image-Base-text_encoder-Q4_K_M.gguf
vae:             your LLaDA VAE
dtype:           bfloat16
vae_tiling:      On

Start with 50 steps / CFG 5.0.

Native Image Editing

The custom nodes support LLaDA-Image's native image-editing mode.

This is not conventional img2img or denoise-strength emulation. The source image is passed through LLaDA-Image's native:

generation_mode="editing"

using its image-conditioning/SigVQ path.

LLaDA Image Loader -----------+
                              |
Load Image -------------------+--> LLaDA Image Edit --> Save Image

Example:

Turn the fox into a white arctic fox while preserving the forest composition and realistic photography.

For Base editing, start with:

Steps: 50
CFG:   5.0

Editing width and height must be divisible by 32.

The same Base transformer and text encoder are used for generation and editing. No separate editing checkpoint is required.

Base vs Turbo

Base:
Steps: ~50
CFG:   ~5.0

Turbo:
Steps: ~4
CFG:   ~1.0

Low-VRAM Notes

• Use the INT8 transformer.
• Use the Q4_K_M GGUF text encoder.
• Enable VAE tiling.
• Use CPU offload when necessary.
• Do not load the original full text encoder alongside the quantized encoder.

Important

Do not load the INT8 transformer through a GGUF diffusion loader. It is native INT8 Safetensors.

The .gguf file in this release is the text encoder, not the diffusion transformer.
